A number of independent efforts have compiled global plant databases on functionally important traits of leaves, stems, seeds, and flowers. These databases are comprised of 1000's to tens of 1000's of species. With a few notable exceptions, they have not been analyzed in an evolutionary or phylogenetic context. However, when synthesized with a modern molecular phylogeny, these data could tell a comprehensive, multivariate story of the evolution of plant functional diversity. In this working group, we will merge multiple databases to explore the rate (tempo, sensu GG Simpson) of evolution of these traits and the best fit evolutionary model(s) (mode) underlying the trait diversification of land plants. We will ask 1. whether important divergences in trait space occurred along similar branches for different traits, 2. whether there were periods of evolution when trait diversification was especially rapid, and 3. whether there were interactions between trait evolution and rates of speciation and extinction. This work will lead to a new community resource of great interest—an internally synced trait matrix—matched with the current state-of-the-art phylogeny. These data can then be synthesized with fossil evidence to explore whether the tempo and mode of trait evolution in extant and extinct taxa provide similar stories. Furthermore, these data will provide a powerful view into the coordinated (or lack thereof) evolution of ecologically important traits across vascular plants—one of the most diverse and important lineages in the world today.
